The CMS detector has undergone extensive improvements in preparation for Run 3 of the LHC to operate efficiently at the increased luminosity and pileup. This includes the installation of a refurbished innermost pixel detector layer, as well as the development of HLT software to make use of heterogeneous computing architectures. In Run 3, track reconstruction at the HLT is based on a single iteration seeded by pixel tracks reconstructed by the Patatrack algorithm, which can be offloaded to GPUs. The HLT track reconstruction performance has been measured in pp collision data recorded at a center-of-mass energy of $\sqrt{s}$ = 13.6 TeV in 2022, in particular during periods with detector condition changes expected to have a significant impact on HLT track reconstruction. The HLT tracking efficiency and fake rate with respect to offline track reconstruction, as well as the impact parameters of tracks reconstructed in the HLT, are presented.
